I have pushed


not to ask for approval yet, but to ask for policy regarding choice of 
javascript methods.

I don't want these mathml tests to be a test of supported javascript but 
I wanted to add some basic tests that didn't just test parsing.

The above just checks that the dimensions of (a span containing) an 
mfrac are the same as the dimensions of the same content with all mathml 
elements replaced by spans. I.e., it just checks that it does 
_something_ with the math.

I used offsetWidth but the specification and implementation of this and 
related methods like scrollWidth etc seems to have had a somewhat 
tortuous history. If the above is acceptable, there are of course 
several other MathML elements that we could test in a similar way, but I 
wanted to test the water first, to see whether this is an acceptable 
testing strategy.

Note the (current) intention here is to keep the mathml-in-html tests to 
purely automatic javascript tests using the provided test harness.

Implementations of MathML are strongly encouraged to also use the MathML 
test suite at


which is a large collection of mainly visual tests against reference 
images, but it seems best to keep that separate at this stage.
